Title: Liquid pump
Inventor: TORII HISAO
IPC: F04C2/10
Filed: 1982-09-09
Abstract: PURPOSE:To obtain a necessary flow amount even in low-speed rotating condition and prevent generation of cavitation in high-speed rotating condition by a method wherein a clutch means is released when a driving shaft exceeds a set rotating number. CONSTITUTION:When the rotating number of an inner rotor rotating shaft 8 is reduced, oil pressure in a delivery port 7 and an oil chamber 13 is reduced, a clutch releasing power, acting on a clutch male plate 12, becomes weaker than the resilient force of a compression coil spring 17 and the clutch 10 is brought into connected condition, thus, the inner rotor rotating shaft 8 is driven at a predetermined set rotating number while repeating such actions irrespectively of the high-speed rotation of an engine. Accordingly, in case the set rotating number of the inner rotor rotating shaft 8 is set below the cavitation generating rotating number of the trochoid pump 1, cavitation will never be generated in the trochoid pump 1. The clutch 10 is interposed in the system of the rotating shafts of the pump 1, therefore, the rotating number of the pump 1 may be held below a given rotating number in the condition of half-clutch and the power loss of the pump may be reduced as much as possible.

Title: Electric power conversion apparatus and smoothing capacitor mounting device
Inventor: HATOSAKI YOSHIHISA
IPC: H05K7/20
Filed: 1990-06-14
Abstract: PURPOSE:To make it possible to maintain, check and replace easily a cooling fan with a relatively shorter life and a smoothing capacitor from the front by installing a fixture hole and a fixture, which penetrate a smoothing cylindrically-shaped and freely removable capacitor from the front side, to a mounting board and threading one end of a support plate into the front side of a heat receiving board and the mounting plate so that it may be freely removed. CONSTITUTION:In an electric power conversion device, a space between a rear side plate 25a and a front side plate 25b of a box-shaped body is air-tightly partitioned by fins 6b with a heat receiving plate 6a facing the back side plate, a mounting plate 21 for a smoothing capacitor, and a support plate 31 for a cooling fan. To the mounting plate are installed a fixture hole and a fixture 10 which penetrate a cylindrically-shaped smoothing capacitor which is freely removable from the front side. One end of a support plate is removably mounted with the front side of the heat receiving plate and the mounting plate with machine screws 31a and 31b. When replacing the smoothing capacitor, it is unavoidable to remove its own bar 24. However, this construction makes it possible to remove the capacitor from the mounting plate easily by loosening a fixture from the front side and replace on a single unit basis as well. Furthermore, one end of the support plate to which a cooling fan 9 is installed, is screwed into the front side of the heat receiving plate and the mounting plate, which makes it possible to remove the cooling fan with the support plate easily from the front side.

Title: Automatic measuring device for inductance
Inventor: FUJIWARA KAISAKU
IPC: G01R27/26
Filed: 1980-11-06
Abstract: PURPOSE:To perform measurement without using a large-capacity battery by supplying a variable-frequency AC current, superposed upon a DC current, to a resonating circuit having unknown inductance, and by detecting the peak frequency of its output voltage. CONSTITUTION:When a measurement start signal is sent from a microcomputer 21 to a saw-tooth wave generator 23, a voltage-controlled oscillator 15 starts oscillating. Its oscillation output is superposed upon a DC current I through a transformer 13, and the resulting current is applied to the parallel resonating circuit having unknown inductance Lx and known capacitances C0 and C1. The terminal voltage of the resonating circuit is applied to a peak holding circuit 25 through a voltage amplifying and shaping circuit 24 and when a peak-value detection signal is sent out of the circuit 25, a frequency measuring instrument 26 holds a current frequency f0. Then, an operator 27 calculates inductance L from the value of the capacitance C0 and the value of the frequency f0. Thus, large-capacity inductance is measured economically without using a large-capacity battery.

Title: Method for fitting lens to resin lens frame
Inventor: KAWAGUCHI YASUHIRO
IPC: G02B7/02
Filed: 1980-11-08
Abstract: PURPOSE:To perform safe and durable securing by fitting a lens into a lens fitting hole of a resin lens frame having a stopper flange part for the circumferential edge part of a lens face on the inner side and securing the lens to the lens frame by using an ultrasonic horn. CONSTITUTION:With a lens 2 held fitted in a resin lens frame 1, the frame 1 is set in a cylindrical anvil 4, after which the leading end part of an ultrasonic horn 3 is brought in press-contact with the top end of the circumferential wall in the lens fitting hole of the frame 1. Thereby, ultrasonic oscillations are given to the frame 1, and the frame 1 is heated at the part pressed by the anvil 4 and the horn 3, whereby melting is caused in the part in press-contact with the horn 3. This melt fills the space between the lens fitting hole and the lens 2. The inside wall of the lens fitting hole bulges to the inner side, thereby contacting with the outside circumferential side face of the lens 2 by pressure. As a result, the frame 1 and the lens 2 are firmly secured.

Abstract: PURPOSE:To enable the formation of a thick interelement isolating film without causing large thermal influence and stress to a semiconductor substrate by forming a material layer having an oxidizing speed faster than the substrate on the substrate and selectively oxidizing the layer. CONSTITUTION:A P-doped polycrystalline Si layer 23 of a material layer having an oxidation speed faster than a p type single crystal Si substrate 21 is accumulated via a thermally oxidized film 22 on the substrate 21. Then, a nitrided Si pattern 24 is formed on the layer 23. Thereafter, with the pattern 24 as a mask B ions are injected to form a p<+> type channel stopper 25 on the substrate 1. Subsequently, with the pattern 24 as a mask the layer 23 is selectively oxidized to form a thick oxidized film 26. Then, the pattern 24 is removed, and remaining polycrystalline layer 23' is removed. As a consequence, the layer 23' is approximately vertically etched, and the polycrystalline Si layer 23'' remains. Thereafter, the exposed film 22 is removed to expose part of the surface of the substrate 21, and is then thermally oxidized. At this time an oxidized film 27 is grown on the exposed surface of the substrate 21, and the layer 23'' simultaneously becomes an oxidized film, and an interelement isolating film 28 is formed.
